WIRE-STRAPPING TOOL.

Application led lApril 14, 1920. Serial No. 373,708.

To aZZ 'whom it may concern.'

Be it known that I, LAYARD` CAMrBnLma citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented certain new and usefulv Improvements in Wire-,Strapping Tools, of 'which` the following is a full, clear, and exact description.. i p

Among the principal objects which the present invention has in view are: To em- ,ploy'continuoua unshaped wire for strap- Figure 1 is a side view showing fragments of a tool 'of the character mentioned, constructed andarranged in accordance with the present invention, showing in conjunction therewith aI crate and wire looped thereabout,'` prior `toy closing or tightening 'the same on the crate around which it has 'been passed, `the broken lines of said figure illustratingv the position of the take-up lever and of the wire strap. when the lever is thrown to the retracted position;

yj 1 VFigure2 1s a detail view on enlarged scale, showing fragments of the takeup lever and toolhandle, together with the twisting head with which the tool is provided; and

Figure 3 is an edge view of the same.

f i Description. Heretofore the usual practice has been to employ bale `wiresor wires having a loop which the crate has been bound. Also the tie formed by over-turning the 1 secondary loophas been unsatisfactory that it is easily opened and loosened.

Another form o-f strap has existed whe-re the straight ends of the-wirestrap have `been drawn together, and twisted upon each other lengthwise of the strap. The tools employed forr accomplishing this have been i objectionable in that they have been exceedingly heavy, thereby taxing the endurance of the mechanic. And furthermore, they have lifted the joined end of the strap from the crate, to permit the making olf the tie, so

that when released from the machine the strap is relaxed'upon the package.

The objections abo-ve mentioned are sought to be avoided by the usev of the present tool, wherein a handle 8 has a laterally-extendedA foot 9, wherein isy pivoted a head 10. The pivotal connection for the head 10 with the foot 9 is formed bythe hollow stud 11,'the end 12 'whereof is overturned to hold the head 10 permanently conneoted` with the handle 8. Thestud 11 is tubular to form a passage through which the strapping wire A is passed.l The tubular passage in the stud 11 opens into the transverse slot 13,y wherein are pivoted the pulleys 14. i i

At 25 I have illustrated aflever which is pivoted to the handle 8 at 26. Lever 25 carries a roller 15 and a dog 16, the latter being pivoted vto the lever at 17.

The wire A is delivered on a reel or other bulk supply, and s threaded between the flange roller 15 and the toothed end of the dog 16. The dog 16 is pivoted by the pin 17, whereon it is rocked by the weighted end 18. The flange 19 of the roller 15 serves to guide the` wire A. Ak further guide is furnished for the wire A by the pin 20, which also serves as the vside of a vdetent jaw when cooperating with the vdog 21. v

The dog 21 is vpivotally mountedby the pin 22 on the handle 8, and is normally set in operative position by the weighted end 2,3 with which the said dog is furnished. Adjacent the pin 20 and dog 21 is an abutment pin 24, which limits the extension of the free end of the wire A as'the same is returned through the passage in the stud l1, and `loetween the pin 20 and dog ,2.1. ln operation the wire A is first threaded between the roller 15 and the dog 16. This operation is facilitated by rocking thel takeup lever on itspivot bolt 26, to a position Where thedog 16 is open, or the toothed end is removed from engagement with the roller 15. YThe wire is then passed above the pin;20,through the opening inthe stud 11, and through the slot 13 between the pulleys 14. From this point it isfextended around the crate B, in the loose form sho-wn by full lines in Figure l of the drawings, and the free end is returned and threaded back through the slot 13, between the pulleys 14 through the stud 11 and between the pin 20 andthe dog 21, until it is arrested by the end of the wire A engaging the abutment pin 24. Thereafter the end of the wire A is held by the dogv2l against retraction.

The operator now draws backward the lever 25, with the result that the' dog 16 rocks to position to engage the wire A, and to hold the same against further'passage therebetween.v The wire A now being held by the lever 25, the slack of the wire A,

where it extends around the package B, is taken up, asv shown by the dotted lines in Figure l. Whenthe wire is drawn in this position, the operator raises the lever 25` to the upright position, the dog 16 releasing the wire A, which is, therefore, n ot fed forward as the ydog moves forward. At the proper position the lever 16 .is again retracted, the dog 16 taking a fresh bite on the wire and drawing on the loop about the package B more tightly. Y

This operation is repeated until the loop about the package B is contracted as tightly as may bedesired. The lever 25 is at this time in a position substantially parallel with the handle 8. The operator now holding the lever and handle 8 in their relative positions, turns the tool about the lstud 11, thel head 10 being non-rotatively held by the wire A as the same extends in opposite directions to opposite sides` of the package B. As the tool is revolved, the portions ofv the wire within and adjacent the head 1,0., up to the pin 20, are twistedupon each other. lIf the rotation is continued, a very tightly andy securely twisted section is obtaine Then this has been effected, the wire A is severed at a' point adjacent to the pin 2 0, andthe tool is then withdrawn yfrom engagement, with the twisted section of the said wire,' which then extends perpendicu larly to the side ofthe package, `This is correctedby means'of a hammer or other tool, which' is used to beat vdown the standard twisted section, or to lay the same parallel with the wire strap at either side of the junction of the twisted ends.

kIt will be noted that the wire lA is still engaged by the roller 15, and dog 16, so `that the tool is ready for the next operation.

r It isv obvious that the herein disclosed which isbeing secured, resulting in the saving of large quantities of wire employed in this art.
